parthchandra opened a new issue, #3801:
URL: https://github.com/apache/datafusion-comet/issues/3801
### Describe the bug
Running TPCDS q23a, q23b, and q36a-v2.7 with Comet enabled causes a native
panic and task failure:
Comet native panic: panicked at
spark-expr/src/math_funcs/internal/checkoverflow.rs:204:17:
fail_on_error (ANSI mode) is not supported yet
**Steps to reproduce**
Run TPCDS q23a, q23b, or q36a-v2.7 with Comet enabled and ANSI mode on
Probable cause -
CheckOverflow::evaluate in
native/spark-expr/src/math_funcs/internal/checkoverflow.rs does not handle the
case with Scalar input -
`(ColumnarValue::Scalar(ScalarValue::Decimal128(...)))`— fail_on_error=true is
not implemented and hits an assert! that unconditionally panics:
In TPCDS q23a, a scalar decimal expression passes through CheckOverflow
with fail_on_error=true (ANSI mode), hits the scalar branch, and triggers the
panic. Because it is a panic rather than a returned error, the JVM receives a
CometNativeException and the entire stage fails with no fallback.
